soroush.asadi 8ddca5647b feat(studio): Phase 3 — scene reorder + numeric duration + FIX/FLEXIBLE gating
Wires the scene-list operations users asked for into the existing timeline
(model-agnostic — works for any scene, layer- or block-based):

- SceneThumbnailBlock: now sortable (@dnd-kit useSortable) with a left-edge grip
  handle (listeners only on the handle so select/rename/resize still work); adds a
  numeric per-scene duration input (commit on blur/Enter, clamped 1–30s) next to
  the drag-resize; a `locked` prop makes it read-only.
- SceneThumbnailStrip: wraps the blocks in DndContext + SortableContext
  (horizontal, 6px pointer-activation so clicks/resize aren't hijacked) and calls
  the existing reorderScenes store action; gates add/browse + reorder/duplicate/
  delete/duration behind isFixedSceneMode(chooseMode).
- studio-store: isFixedSceneMode() helper (single source for FIX vs FLEXIBLE).
- i18n: reorderScene / durationLabel / secondsUnit in fa + en.

Verified with `npm run build` (rules-of-hooks clean). NOTE: a THEME PICKER and
FlexStory block-FIELD editing are deferred — the studio editor is Konva-layer-
centric, so both need a FlexStory-aware editing path (a follow-up), not this phase.

Repo Path Purpose
flatrender D:\Projects\flatrender This repo — Next.js app
flatrender-admin D:\Projects\flatrender-admin\admin-api .NET 10 Admin API
flatrender-admin D:\Projects\flatrender-admin\admin-ui React Admin SPA

Stack

  • Next.js 15 App Router · TypeScript · Tailwind CSS · shadcn/ui
  • Supabase — auth, database, storage
  • Stripe — subscription payments
  • React-Konva — canvas editor (video + image)
  • next-intl — Persian (default) + English i18n
  • ffmpeg.wasm — browser-side video trimming
  • nexrender — server-side After Effects rendering

Environment Variables

See .env.example for the full list. Minimum required to run:

NEXT_PUBLIC_SUPABASE_URL=
NEXT_PUBLIC_SUPABASE_ANON_KEY=

Without Supabase the app runs in mock mode (studio uses localStorage).

Database Migrations

Run in order in Supabase SQL Editor:

  1. supabase/migrations/001_profiles.sql
  2. supabase/migrations/002_render_jobs.sql
  3. supabase/migrations/003_projects.sql

Admin Panel

The admin panel at D:\Projects\flatrender-admin manages templates, categories, and media. When ADMIN_API_URL=http://localhost:5000 is set, the Next.js app fetches live data from it. Without it, hardcoded fallback data is used.

See CLAUDE.md for full development guide.
